Answer:


x^(3)/(5) = (x^3 )^(1)/(5)


x^(3)/(5) = \sqrt[5]{x^3}


x^(3)/(5) = (\sqrt[5]{x})^3

Explanation:

Given


x^(3)/(5)

Required

The equivalent expressions

We have:


x^(3)/(5)

Expand the exponent


x^(3)/(5) = x^{ 3 * (1)/(5)}

So, we have:


x^(3)/(5) = (x^3 )^(1)/(5) ----- this is equivalent

Express 1/5 as roots (law of indices)


x^(3)/(5) = \sqrt[5]{x^3} ------ this is equivalent

The above can be rewritten as:


x^(3)/(5) = (\sqrt[5]{x})^3 ------ this is equivalent
